Specification of Letters Patent.

Patented July 28, 1914.

Application filed January 9, 1913. Serial No. 741,031.

T 0 all whom it may concern-.-

lle it known that I, EDWARD C. Gnnnmnn, citizen of the United States, residing at Galion, in the county of Crawfordand State of Ohio, have invented certain new and useful Improvements in Unloading Devices, of which the following is a specification.

My invention relates to new and useful improvements in systems for unloading and storing coal, crushed rock, gravel, sand or other loose cargoes from cars and the object of my invention istoprovide a system by which said cargo may be expeditiously and conveniently handled.

A further object of my invention is to provide in connection with a car track having bins formed between the rails to receive the cargo discharged through the swinging bottoms of the cars, a portable storage bin movable in spaced relation to the track and having an inclined track leading from the bin along which a bucket or container is 1novably mounted.-

A further object of my invention is to provide means for discharging coal from the bin into the bucket to fill the same, for raising the bucket along its tracks and for then discharging the contents of the bucket into the storage bin.

A further object of my invention is to provide means for automatically controlling the loading and unloading of the bucket.

With these and othervohjects in view, my invention will be more fully described, illustrated in the accompanying drawings, and then specifically pointed out in the claims whicliiare attached to and form a part of this application.

In the drawings: Figure 1 is an elevational view, partially in section, showingthe' improved system in operation; Fig. 2 1s a fragmentary elevation upon an enlarged scale, showing the arrangement of pulleys upon the storage bin for the hoisting cables; Fig. 3 is a fragmentary top plan view of the structure shown in Fig. 2; Fig. 4 is a vertical sectional view taken through a modified form of cargo handling bucket; Figs. 5 and -6 are fragn'lcntary side elevations, showing the manner in which the bucket itself, during its movement, controls the gate governint, the discharge from the bins between the rails to the bucket.

Corresponding and like parts are referred E to in the following description and indicated reference characters.

My improved invention, in its aim lest form, is clearly illustrated in in which the railroad track is shown in section,

the rails 10 of the track being supported in the usual manner upon spaced ties 11. Bins 12 are formed immediately below the ties and between the rails 01 the track, extend ring at one end beyond the side of the track, as shown. These bins preferably all communicate with each other at their lower ends and are provided with an inclined bottom 13, preferably formed oi metal. At the outer end of the bin, is a pair of spaced guides 14 in which is slidably mounted a plate 15 forming a gate. The coal, crushed stone or other cargo of a car isemptied into these bins through the dumping bottom of the car in the usual well known manner, the car being conventionally shown at 1 6 and aportion of its ,cargo in the bin at 17. I

The bin beyond the gate 14 is deepened as shown at 18 and provided with an upwardly and outwardly inclined outer Wall 19, this deepened portion of the bin permitting the positioning of a carg0-carrying-bu0ket at a level below that of the lower end of the ini clined bottom 13 of the bin proper in such a position that upon the raising of the gate 15, the material contained in the bin 12 will slide along the bottom 13 and into the bucket to load the same.

A movable storage bin, indicated as 'a whole by the numeral 20, includes a. supporting frame 21 mounted upon wheels 22 i. such a manner that it may be, moved in parallel spaced relation to the track to bring it opposite the various portions of the bin and this frame carries the substantially rectangular shaped bin adapted to receive and store the coal or other cargo, the bin being provided at one side with a discharge chute 23 having a swinging gate 24 adapted when held in normal position by a latch 25 to preventvdischarge of the contents ofithe bin. Any suitable form of prime mover, such as a gas engine is also carried by the frame 21., such an engine being shown at 26 and this engine is not only adapted to raise and lower the bucket to convey the coal from the delivery bin to the storage bin but may be also arranged to drive the storage bin itself,

in all the views of the drawings by the same meme-1 illi'nfllli-FFfiBi in the manner described.

The sides of the chute 55 are provided in their upper faces with notches or seats 58 adapted to receive-the free end of a pivoted catch 59 carried by the extension 56 of the chute and to normally hold the said extension in raised position, the catch 59 being heldin engagement against the upper faces of said sides by springs 60. I

Pivoted by means of upwardlyextending cars (31 formed one upon either side of the body portion, is a trip member 62, the body portion, of whicli'extends downwardl into the bin-18 in such a position as to e ongaged and swung rearwardly by the bucket. durin ,the downward movement of the lat-' ter, t is tri "snemlmr being normally held inv forward" )osition by a spring 63. The cars (trot-this trip member carry arcuate fingers'64 which in normal position of the gate or chute extension 56 and trip member 62 engage against the lower'faces-of the latches 59, as shown in Fig. 5 of the drawmgs.

Upon lowering the bucket 4.0 or 48, as the case. may be, said bucket passes by the extension 56 of the chute and engages the trip lever and swings the same "rearwardly and this swinging of the trip member acting through its fingers ()4 to release the latches 59 and permit the downward swinging of the extension 56 of the chiite, this swinging beingcaused by the pressure of the. coal or other material in the bin. \Vhcn the bucket has become nearly full, the engine is started to raise the same and during its upward movement, the bucket engages the chute extension 56.to raise the same until it. is; locked infits original position by the latches 59, thus cutting off all further escape of coal or other materia'lfrom the bin. Upon the raising of-the bucket, the trip member 62 is swung forward again by its spring and the device is agflin; eady for operation.

- It will t ere ore be seen that when the system is equipped with the chute structure own in Figs. 5 and 6, the entire unloading and storing of the cargo may be ace ".1.- plished by a single person, this erson o crating the engine and manipulating the 9: or two levers required to control the a'ctn-u of the windin drum.

The above described cargo handling sunstem is therefore not only simple and effi'cient, but also inexpensive in operation.

It'will of course be understood that I do not wish in any way to limit myself to the specific details of construction illustrated in the drawings and described in the above specification, as any changes in details of construction, found desirable, may at any time be made without in the slightest degree departing from the spirit of my invention as set forth in the appended claims.

Having thus described the invention, what is claimed as new is: v

1. A cargo handling system including an inclined track, a bucket movable along the track, a chute directed toward the ower ortion of the track, an extension swingingly mounted upon one end of the chute, a spring pressed pawl carried by the extension and engaging the chute to'normally hold the extension in position to prevent the passage of material through the chute, a swingim member mounted upon the exten sion an. projecting into the path of the bucket, and a pawl engaging finger carried by said member and arranged to release the pawl when said member is engaged by the bucket. r

2. A cargo handling system including an inclined track; a bucket movable along the \pawl when said member is engaged by the bucket, said chute extension, upon release, projecting in the path of the bucket. upon its return, w iereby the bucket raises the extension to close the chute.

In testimony whereof I aflix my signa-. ture in presence of two witnesses.
